| Description | Nigericin sodium salt is an antibiotic, an NLRP3 activator, and a cationic ion carrier. Nigericin sodium triggers the activation of the NALP3 inflammasome, which inhibits Golgi function and suppresses the growth of Gram-positive bacteria. |
| In vitro | 方法:三阴性乳腺癌细胞 MDA-MB-231 和 4T1 用 Nigericin sodium (0.25-20 μg/mL) 处理 24 h,使用 MTS 方法检测细胞活力。结果:Nigericin sodium 剂量依赖性抑制 MDA-MB-231 和 4T1 细胞的细胞活力,IC50 分别为 2.881 μM 和 2.505 μM。[1]方法:人肺癌细胞 H460 用 Nigericin sodium (1 μM) 处理 24-48 h,使用 Transwell 方法检测细胞迁移和侵袭情况。结果:Nigericin sodium 显著抑制 H460 细胞的迁移和侵袭。[2] |
| In vivo | 方法:为检测体内抗肿瘤活性,将 Nigericin sodium (2 mg/kg,皮下注射,每两天一次) 和 anti-PD-1 (250μg/只,腹腔注射,每周一次) 给药给携带三阴性乳腺癌肿瘤 4T1 的 BALB/c 小鼠,持续两周。结果:单独的 PD-1 抗体没有显示出显著的抗肿瘤作用,而 Nigericin sodium 显示出中等的抗肿瘤效果。Nigericin sodium 和 anti-PD-1 的组合几乎完全抑制了肿瘤生长。[1]方法:为研究衰老对炎症小体功能的影响,将 Nigericin sodium (0.005 mg/g,250μL) 单次腹腔注射给流感病毒感染的 BALB/c 小鼠,每天一次,持续七天。结果:在流感感染期间用 Nigericin sodium 治疗增加了 IL-1β 的产生,增加了 capase-1 的活性,并降低了老年小鼠的发病率和死亡率。在流感病毒感染期间,老年小鼠的 NLRP3 炎症小体活性受损,Nigericin sodium 治疗可以挽救老年宿主的 NLRP3。[3] |
